Resumo
The objectives of this study were to comparatively quantify length and biomass of fine roots (≤ 2.0 mm)
in the soil profile (0-10, 10-20, 20-30, 30-40 cm) and in the litter of a 15-year-old Pinus taeda L. stand,
as well as in an adjacent Grassland area. The samples were obtained through monolith excavation. Roots
were separated through washing and collecting and were then distributed over a white sheet of paper, where
images were obtained with a digital camera. Using the software Image Tool for Windows version 3.00© the
images were processed to quantify root length. Subsequently, roots were dried in a stove and, weighed to
determine the biomass. The vegetation in the Grassland area showed 234.28% greater density of fine roots
than the adjacent area where the Pinus taeda L.stand is located.
